ELEKTRA DM20 Heating Cable

Floor heating under different surfaces

The ELEKTRA DM-20 Twin In-Screed Heating Cable is used primarily in existing homes with either cement or timber floors where the heating is provided by in-screed cables. It features a single sided power supply and is controlled by an electronic thermostat.

It is installed on top of an existing floor in a cement screed or self-leveling compound of approximately 6-8mm thick * and can be installed under many different floor surfaces which radiate heat easily, such as tiles, slate, stone, low pile carpet and some wooden floor panels **.

* NOTE: where carpet is to be installed over the heated floor, the cable must have a screed to a minimum depth of 15mm. This is to allow adequate dispersal of heat and to prevent potential damage to the heating cable.

** IMPORTANT: Not all timber floors are suitable for under-tile heating systems – please check with your timber flooring manufacturer to see how their product performs with floor heating. See – for example » BT Bamboo installation guide

Quick response

The ELEKTRA DM20 is a ‘quick response’ heating system and if the room has effective thermal insulation it may be used as the primary heating system.

This form of heating is very popular in bathrooms and toilets where it provides warmth underfoot and keeps your towels and floors dry and free of mould.

The heating alternative for new bathrooms

There is also an emerging trend towards using under-tile heating cables like the DM20 for bathrooms and ensuites in new homes – even where other forms of heating are used in the main living areas.

This is partly due to the relatively inexpensive cost of installation and the fact that thermostat design and distribution of heat within the cement screed makes our systems very efficient.

Note: The ELEKTRA VCD and DM twin cable design eliminates the potential for electromagnetic radiation which may be an issue with older single cables in some circumstances.

ELEKTRA VCD and DM cables are also compliant with new electrical wiring regulations AS/NZ3000/2007.
